Southland offers some of New Zealand's wildest 4WD tracks, from sweeping coastal drives along Oreti Beach to the remote valley and forest roads winding toward Fiordland's edge. Expect river mouths, windswept southern beaches, and backcountry access through the Catlins and beyond. It's rugged, weather-exposed terrain that rewards well-prepared overlanders chasing that true end-of-the-world feeling.
